This invention relates more particularly :07,

lighting fixtures of general adaptability, and

it is among the objects of the invention to pro; 1

vide a construction capable of holdingstand V a-rd lamp equipment, andin a manner posi I I V tive and simple. Other ob eotsand advantageswillappear as the descriptionproceeds. To the accomplishment of thetoregolng and related ends, the invention, the-n, con- Sists of thefeatures hereinafter described,

view showing an'embodiment of the invenj tion; Fig. 2 is a rearelevational'view; and

Fig. 3 is a similar view with another form of 1 socket i The referencecharacteril in the drawing 7' designates awall plate or canopy made upof glass, porcelain, or other suitable material,

' r and having attaching means, for instance, a

, plate or strip 2 seating ateach end in recesses 3 and held by screws4. a The member 1 1s provided with a central bore, the inner part 50fwhich extendsto a ledge or shoulder 6, preferably byflaslightconvergence or taper and the reduced outer portion 7 of which iscylindrical. Externally it is screw-threaded, and engaging on suchthread is a clamp-ring 8 which on being set up from the inside of ashade 9 ofany desired i'orinholds its securely against the canopy. Thebore 5, is adapt- {ed to receive a lamp socket S, a lateral recess 40,10allowing the seating of. a lug projection 11 thcreofiand this togetherwith the wedging taper of the bore, where availed of, holds the. socketagainst turning, and in this manner standard keyless,-key or pull chainsockets Where a pull-chain socket is used, the. chain-guide 12 thereofseats in the recess 10, and the chain extendsout through thej opening13. Ordinarily an additional securing means forthe socketis desirable,and

V for this, a clip orthe like 14: may be fastened iby ascrew or. bolt;to the canopyinside'so as tolap over back of the socket as in place inthe bore;

It will thus be seen; that the constructionas a whole providesa;shadeholder adaptable to shades of wide variety of contour and size,and using standard sockets, without necessity of any additional adapterelement or' modification of the socket. I Moreover by rea- .sonof themanner of fastening the socket,

that is, entirely within the canopy, there is no danger of the socketbeing displaced when.

a lamp ischanged or when the shade is taken off orreplaced, the holdingmeans in each instance being entirely independent.

Other modes of applying the principle on CLEVELAND, l 01:10, nssrenons'ro THE the invention may be employed, change being made as regards thedetails disclosed, provided the means stated in any of the followingciaimsor the equivalent of such be'em: ployed.- I

lVe therefore particularly point out and distinctly claim as ourinvention i 1. In a lighting fixture, the combination of a canopy havinga bore to hold a lampsocket, and clip means attached to the canopy forrestraining the socket against rearward displacement;

2. In a lighting fixture, the combination of a canopy having a bore tohold a lamp socket,

and a swingableclip back of'the socket and fastened to the 1 b canopyforsecuring the socket in tne ore. i

- 3 In a lighting fixture, the combination of a canopy hav ng anun-turnable external thread at its outer end, and a clamping ringengaging thereon for securing a shade,said canopy having a bore toreceive a lam socket,

socket against turning.

andmeanswithin the canopy for 1101 ing the 4. In a lighting fixture, thecombination of a' canopy having an un-turnable external thread andhaving a bore with a lateral recess at the rear portion to hold 'alampsocket and socket projection respectively, a clamping ring engageable onsaid external thread for a canopy externally threaded at itsouter end,

- securing a shade, and means behind the socket j for securing thesocket in place. W

.5. In a lighting fixture, the combination of a elampingring engagingthereon for securing a shade, said canopy having a tapered bore toreceive a lamp socket, and means back of the socket and secured to thecanopy for holding the socket in the bore.

6; In a lighting fixture, the combination witha canopy having a bodyportion and being reduced and externally threaded at its outer end witha shoulder, a back plate for said cano y; and fastening screws for saidback plate extending through said shoulder, of a shade having a neckportion fitting over said end and an internally threaded clamping ringengaged With said end interiorly of said neck and holding said neck inclose abutment with said shoulder and in concealing'relation to saidscrews.
